History of Kombucha
Chinese origins
Kombucha originated in ancient China during the Qin dynasty (220 BC). At the time, this drink was called the "Elixir of Life" and was consumed for its supposed health benefits. Emperor Qin Shi Huang, who reigned in the 3rd century BC, is said to have discovered its virtues and encouraged its consumption throughout his empire.
Ancient Chinese writings referred to it as a "divine tea," praising its medicinal properties. This legendary status allowed kombucha to gradually spread to other regions, eventually reaching the West.
Travel to Europe
At the beginning of the 20th century, kombucha gained popularity in Europe, particularly in Russia, where it was used as a remedy during World War I. However, its spread was hampered by sugar rationing during World War II. These historical periods marked the beginnings of kombucha's introduction in Europe, paving the way for its strong return in the next decades.
Current status
Today, kombucha is experiencing a notable resurgence in interest, particularly in France. This growing popularity can be explained by several trends:
- The craze for fermented foods
- The search for natural drinks to replace industrial sodas
- Increased focus on gut health and overall wellbeing
In California in the 1960s, kombucha also experienced a resurgence. Today, it has established itself as a popular alternative to traditional sugary drinks, meeting the expectations of health-conscious consumers.
"There is a wellbeing and artisan aspect that is becoming increasingly appealing, replacing hyper-sweet sodas." -R-Kombucha
This development reflects a more general trend towards more natural and responsible food choices, making kombucha one of the most promising beverages in the current landscape of alternatives.
How is Kombucha made?
The main ingredients
To make kombucha, you will need four key ingredients:
- Tea (black or green tea): it provides the tannins and nutrients essential for nourishing microorganisms.
- Sugar (white or cane): essential for activating fermentation.
- Water: the basis of the preparation.
- SCOBY ( Symbiotic Culture Of Bacteria and Yeast ): a live culture of bacteria and yeast , often referred to as the "kombucha mother."
The stages of fermentation
The production of kombucha involves two distinct phases:
-
First fermentation (F1)
This step takes between 10 and 15 days at room temperature (68-77°F). Start by preparing sweet tea, which you let cool before adding the SCOBY and 10% kombucha from a previous batch. -
Second fermentation (F2)
This phase is optional and lasts 2 to 5 days. The kombucha is placed in airtight bottles to develop more complex flavours and natural effervescence.
These steps ensure a balanced and well-fermented beverage.
Final product features
This is what a well-realised kombucha looks like:
| Appearance | Description |
|---|---|
| Drop | Tart with a slight fizz |
| Texture | Natural effervescence |
| Colour | Depends on the type of tea used |
| Aroma | A subtle blend of vinegar and tea notes |
Success factors
For a quality kombucha, it is crucial to respect these points:
- Maintain impeccable hygiene.
- Ensure a stable temperature.
- Use a healthy SCOBY.
- Choose high quality ingredients.
During fermentation, sugar is transformed into beneficial enzymes and acids, creating a lively and balanced drink.
Health Effects and Benefits
Digestive Health
Kombucha, thanks to its high probiotic content, supports the gut microbiota and helps reduce the presence of unwanted microorganisms. Drinking a glass after a meal can aid digestion. What's more, with a sugar content of 30 to 50 g/L, it is much less sweet than sodas, which contain between 100 and 130 g/L.
Antioxidant content
The quantity of antioxidants varies depending on the type of tea used and the duration of fermentation. Here is an overview of the key data:
| Type of Kombucha | Polyphenols (mg/L) | Antioxidant activity |
|---|---|---|
| Green tea | 320,12 | Very high |
| Red tea | 395.9 (pre-fermentation) | High |
| White tea | Moderate | Average |
| Black tea | 183,12 | Moderate |
Fermentation boosts antioxidant activity, increasing it by about 40% after 21 days. These antioxidants help combat oxidative stress, often linked to modern lifestyles. This feature distinguishes kombucha from other drinks aimed at promoting wellbeing.
Comparison with other Drinks for Wellbeing
Kombucha stands out thanks to its nutritional composition, which includes:
- Vitamins: B1, B2, B6, B12, and C
- Minerals: iron, manganese, nickel, and zinc
- Probiotics: beneficial live cultures
A few recommendations:
- Opt for kombuchas with less than 4 g of added sugar per serving.
- Keep them cool once fermentation is complete.
- Choose certified products to limit the risk of contamination.
Matcha tea and Kombucha
Matcha tea and kombucha share several benefits for wellbeing: both are rich in antioxidants and nutrients that are beneficial to the body. While kombucha must ferment to develop its probiotics, matcha immediately offers a high concentration of catechins and L-theanine, promoting relaxation and concentration. Together, these two super ingredients can be the perfect combination for a healthy and balanced lifestyle.
